Problems solved by technology

In "Peer-to-Peer Networking and Applications" 2019, 12(5) "Smart contract for secure billing in ride-hailing service via blockchain", Huajun Zhang et al. proposed a blockchain-based security bookkeeping protocol for passengers and The driver negotiates the boarding location, route and fare to prevent malicious drivers from deliberately detouring or prolonging the service time. However, the calculation cost of this solution is relatively high, so none of the above solutions is suitable for safe shared travel services

Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0040] 1. Model structural layout of the present invention.

[0041] Such as figure 1 For the overall structure of the present invention, the specific parameters are defined as follows:

[0042] Trusted Authority (TA): It is mainly responsible for the initialization of the system, generating keys for roadside units and users, arbitrating and scoring disputes and revealing the identity of malicious users, assuming that TA is not easy to be captured and is completely credible.

[0043] Roadside Unit (RSU): As a fog node with large storage space, strong computing power and network communication capabilities, the roadside unit node performs shared travel matching according to the information sent by passengers and drivers. The side unit re-encrypts the itinerary ciphertext to generate a re-encrypted ciphertext that the driver can decrypt.

Abstract

A safe shared travel service solution based on the consortium blockchain, including trust agencies, roadside units and users, where users are composed of passengers and drivers. Passengers encrypt the itinerary data and access structure to generate ciphertext and send it to the roadside unit, and the driver sends his own itinerary attributes to the roadside unit, and the roadside unit uses fog computing to match passengers with suitable drivers and convert the ciphertext into re-encrypted ciphertext After sending it to the driver, the driver decrypts the re-encrypted ciphertext to obtain the information and provide passengers with shared travel services. After the shared travel service is over, the roadside unit will store the shared ride records on the blockchain for traceability and accountability in case of disputes. The invention satisfies the safety and privacy requirements of the shared travel service, effectively resists potential collusion attacks, not only changes the centralized structure of the existing shared travel service scheme, but also reduces communication and calculation costs.

Description

technical field [0001] The invention belongs to the technical field of information security, and relates to block chain technology in the field of information security, and methods for re-encryption by attribute proxy and data security verification. Background technique [0002] With the development of sharing economy and Internet technology, shared travel has become a new way of travel. In recent years, shared mobility service providers such as Uber and Lyft have provided shared mobility services to millions of users in hundreds of cities. As the largest shared travel service provider in China, Didi Chuxing has 450 million users and provides users with an average of 20 million shared travel services every day. Passengers and drivers publish their own itineraries on the app, such as departure and destination, shared travel service providers match supply and demand based on the information released by passengers and drivers, and then send relevant information about the drive...
